SC Grade
Dedicated seed-coating form: low-dust, biocide-free, water-activity controlled per batch.
Launching 2026 Seed & agriculture
Effect Pigments for Seed Coating
Identification, not decoration. Microplastic-free pearlescent pigments for brand recognition, anti-counterfeiting and sowing visibility — engineered and stocked in the EU.
Regulatory window
The Microplastic Deadline Is Your Opportunity
EU Regulation 2023/2055 restricts intentionally added microplastics. Seed coatings without plant protection products must comply by October 2028; treated seeds by October 2031. ChemTech pigments are inorganic mica-based materials — outside the definition of synthetic polymer microparticles by design. No reformulation risk, no transition anxiety.

Oct 2031 treated seeds

Dust suppression in the upcoming SC Grade will be microplastic-free as well.

Anti-counterfeiting
Three Levels of Protection Against Counterfeit Seed
Three independent security features, combined in a single coating or applied separately: a signature pearlescent effect that is hard to imitate, a hidden inorganic UV marker invisible in daylight, and a spectral fingerprint per batch. Ask us how premium seed brands protect their hybrids.
Ask about brand protection
Single-layer coating: a blend of organic pigments, CTA82 StellarSatin Silver and a special UV marker.

What Does It Really Cost per Hectare?
Pearlescent pigments look expensive per kilogram — and cost cents per seeding unit. Check your numbers.

FAQ
Questions Seed Technologists Ask
Do pearlescent pigments affect germination?
Mica-based pigments are chemically inert and insoluble. At typical dosages (1–3% of the coating) they do not affect germination or vigour. ISTA germination data for our SC Grade is being generated and will be published here.
Will flake pigments increase dust-off?
Fine fractions (5–30 µm) are selected to anchor in the film former at recommended dosages. Comparative Heubach dust-off data in model coating (current Euroseeds method, ring-tested laboratory) — in progress, H1 2027.
Are your pigments microplastic-free?
Yes. Mica-based pearlescent pigments are inorganic materials outside the SPM definition of Regulation 2023/2055. A signed MPF Statement (CT-REG-001) is available for download.
Does “fluorphlogopite” mean the pigment contains PFAS?
No. Fluorine is a structural constituent of the inorganic synthetic fluorphlogopite lattice; total fluorine is therefore not a PFAS indicator for this product. No organofluorine compounds are used or intentionally added; the products contain no carbon–fluorine bonds. Full FAQ on the CTA Series page.
What about heavy metals?
Guaranteed heavy-metal limits per element (incl. Ni, Cr(VI), Tl) — available on request. Formal Statement (CT-REG-022) to be issued with accredited ICP-MS verification, Q4 2026. Request current limits
Are coated seeds compatible with optical sorting?
Pearlescent coatings change seed reflectance in a consistent, characterisable way. We can provide reflectance data and support sorter calibration during trials.
What are your minimum order quantities?
Sampling from 100 g, pilot lots from single-bag quantities, production from stock in Riga. Small enough to trial, fast enough to scale.
Can we get an exclusive shade?
Yes — we reserve custom grades per customer within a defined crop segment. Ask your technical sales manager for terms.
